Determination of the reaction order (half) with respect to HA = p-CF3-PhOH, using a log(kobs) versus log([HA]) plot, for the proton-assisted formation of [FeIII(SMe2N4(tren))(OOH)]+ (2) in the reaction between [FeII(SMe2N4(tren))]+ (1) + (18-crown-6-K+)(O2−) in THF at −78 °C. [O2−] = 0.35 mM, [FeII] = 6.5 mM.
